昨天做了个小型的数据库管理系统,主要是用于管理货物的进出和统计
使用MySQL和java作的,由于是帮其他不会编程的人写的毕业设计,于是今晚打算用jdk里面自带的javaDB
来实现一下,方正比较简单,争取2个小时拿下。
hoho~~~
昨天晚上做的太失败了,作了一晚,哎。。。十分垃圾
刚才花了下时间看了下help
oh,my God,我真是个苦命的孩子,居然花大量的劳动力去写
本来可轻松搞定,真是社会的进步阿
自己跟不上了,人老了。。。
首先看了下javaDB, 连是连上了,但加奇怪的是Drivers用不了,
什么都没错吗,真是的。。。
哎,原来是重装netbeans后点击保留配置的结果。
因为安装glassfish-v2ur2来代替了以前的glassfish-v2,这样以来路径就不对了
当然驱动的jar包就Error了,自然就不可以使用了,于是配置了下就ok了。
虽说ok,但是Java DB(Embedded)connection has some problems
废话不说了,现在开始狂建数据库吧。首先把那5张表搞定
oh,出现问题拉。。。
Java DB中建的表正错了杂就删不了阿,呵呵,重启就ok了,原来是我先把文件给删除了。。。

一堆异常,而且把插入的table bind删了还是不行,恢复历史版本也不行,把我折腾残了,于是只能不断的新建工程,大量的劳动力被浪费了
后来发现原来可以有ctrl+z就ok了,
可一把table绑定好date就有抛异常哦
经过一宿的折腾,终于发现是database建的有问题,
表中的列用了关键字,在MySQL中建的时候没有发现,因为没有任何的异常现象。。。
真是晕死。。。。
大概是因为里面用了引号,而bind中是没有的吧。。。
不过还是因为自己,乱用什么关键字阿。
这个bug解决后,参照自动生成的代码,就很快搞定了,
下面还要帮00写下他家的种子系统。。。
呵呵,不知道我四娘需不需要化肥管理系统阿???
不过都是一类系统了。。。
哎。要考软设了,还没看阿
想起上次的成绩就欲哭无泪,自己没看。。。不过下午考试看不看都一样,,,
这次还是要好好的复习了。。。
还有四级。更是晕阿,考了2次。。。
以后要好好规划我的生活了。。。
早上看哈英语和日语
下午浏览哈网页,写哈程序。。。
晚上看软设。。。
that's all
